When I see Patrik Schumacher (business partner and factotum of Zaha Hadid) speak about architecture, I get very sad for him. He looks like a member of Kraftwerk trapped in one of those kidnap videos released by organisations with names like Swords of the Righteousness Brigade. ‘Parametricism is the great new style after Modernism,’ he says in a talking head film in the main exhibition of this year’s Venice architecture biennale. He looks as though someone is pointing a Kalashnikov at his kneecap just out of shot.
